Compact Forged Valves
These types of valves are mostly forged steel. The body of valve is constructed by welding of all parts except stem housing. No sealing elements are used which might cause leakage through. Inspection and maintenance of such valves may be executed on live line. When required it can be manufactured from special material according to NACE corrosion standards and/or temperature class.
Compact Forged Ball Valves
Full Welded Ball Valve, Floating with Cap/Lever Underground Type - E604
It is ideal type for vent, drain, by-pass, take-off applications. Its control is capped and it doesn’t allow operation without opening the cap. It is often used in pipelines, for underground postions.
It can also be used as to impel to Gas Over Oil Hydraulic Actuators.

Compact Forged Gate Valves
Gate Valve Bolted Bonnet, Rising Stem - E504
This is a closure valve. It is not used to adjust or throttling the flow. If needed, Globe Valve should be used beside it.
If often open-close application is necessary, Ball Valve should be preferred.

Compact Forged Plug Valves
Plug Valve, BC Inverted Plug, Lubricated - E104
This type is designed to discharge the trapped pressure under control. It is preferred for purge, blow-off, by-pass, blow-out operations.
Depending on the usage frequency, it needs to be lubricated. It is not recommended to be used without a lubricating film in between the body and the plug.
This valve can be used for throttling and adjusting the flow. It is not the type advised for closing, and this is why it should be isolated with Ball or Gate valves.
